That cute face. Must kiss.

Now look you went and spoiled her. Now every time she wants her ear scratched she’s going to threaten to plunged the mortal world into eternal night, casting an entire universe into an endless void, unmaking all of creation. I hope you’re happy. :[
 
(See Nicemare Moon’s expression in the last frame)
 
Uhh.. You know uhh if you know your hand were to become tired at any point, I could like take over ear scratching duty. Uhh you know for the good of the universe in such. O///O

I’m just trying to think…there weren’t ANY G3/G3.5 villains at all, and of the G1 villains….hmm, it might’ve worked on Catrina, broken the corrupting effect her magic potion had on her.
 
 
Tirac, the Witches from the Volcano of Doom, the Smooze….maybe on Aaaaaaarg, he was certainly ticklish for a giant spider, maybe soft scritchies would’ve worked too? xD Bumble the Queen Bee, Porcina, that troll with the magic coins, Bright Eyes (but not Zeb, no way), and Crunch the Rockdog, they all became good in the end, so ear scritchies might work on some of them but I’m not sure I’d want to test that theory myself… :P

Too bloody true, that. Owch.

@Gundlach  
actually that will probably only work on generation 4 villains like nightmare moon or queen chrysalis and MAYBE discord, anyone else would slowly turn towards you, give you a “the fuck are you doing look” and probably beat the ever loving crap out of you.

@Changeling#209458  
Then either it’s an amorphous blob, or entirely too evil to be cute. Either one is not to be trifled with.

What if it has no belly?

@Napsack  
Failing that, belly rubs (if applicable) are fine too, usually.

@PonyPon  
Aim for just under the chin instead.

@PonyPon  
Hope for the best and run like hell

@Gundlach  
What if it has no ears?
